Page 7: Overview
• Four 1.5V alkaline AA batteries. • Neoprene carrying case with belt clip. The TuffSat oximeter is capable of printing data through an infrared link to the optional Hewlett-Packard® Infrared Printer (HP 82240B). For information on ordering and using this printer with the TuffSat, see the appendix: Printer Features and Use. -
Page 8: Trutrak Data Sampling System
TruTrak data sampling system ® The TruTrak data sampling system, patented by Datex-Ohmeda, enables the TuffSat oximeter to calculate SpO many times each second through advanced statistical data processing. While other oximeters calculate only at the peak and trough of each waveform, the TuffSat assesses SpO continuously. - Page 9 Overview The two light wavelengths generated by the sensor light source (the red and infrared LEDs) pass through the tissue at the sensor site. The light is partially absorbed and modulated as it passes through the tissue. Arterial blood pulsation at the sensor site modulates transmission of the sensor’s light.

Page 10: Calibration
Two different methods of calibration are currently used by manufacturers of pulse oximeters: fractional and functional. Important: The TuffSat pulse oximeter uses the functional calibration method. The user cannot change the calibration method to fractional. Functional saturation is represented mathematically as the percentage of hemoglobin capable of carrying oxygen that is carrying oxygen. -
